Calculate the number of moles of sodium...

Calculate the number of moles of sodium (Na) atoms present in ` 11.5` g of sodium.

Text Solution

Verified by Experts

Number of moles of sodium atoms `=("mass of sodium ")/("Gram Atomic Weight") = (11.5)/(23) = 0.5`
i.e., 0.5 moles of Na atoms are there in the given 11.5 g sample.
